Thermal resistances offered by both are different.

Heat transfer by conduction depends on area, areas of sphere and cylinder are different.

The area of the cylinder is 2*3.14*r*l.
The area of the sphere is 4*3.14*r^2*l.
So will get different values of heat flux.

Simple answer is the area through which heat is transferring are different.

Sphere and cylinder area's are different.

In cylinder, it follows logarithmic nature while in sphere it follows hyperbolic, don't it be same.

I think both areas of sphere and cylinder are different.

Regardless of the different areas, both are clearly said to be solid objects.
How else will heat move around, Would you say its by radiation or convection?
